Proportional servo valve, description about (ARBURG) servo valve D681Z4707B on China Suppliers Mobile

Product Description

D680 series servo proportional valve is used in two-way, three-way, four-way and five way throttle type flow control valve. They are suitable for electro-hydraulic position, velocity, pressure or force control systems and other systems requiring high dynamic response. D680 series integrated circuit board is also an innovation, it uses SMD technology and 24VDC power supply. - direct acting pilot valves do not require pilot stage leakage flow. This can achieve a large amount of energy saving, especially for systems with multiple valves. - the dynamic performance of direct drive valve is not affected by the change of working pressure. - reliable operation. The excellent pressure gain of the pilot valve with valve core and valve sleeve provides high valve core driving power for the long stroke main valve core. This ensures that the position control of the main valve core can be strengthened even under the strong fluid power and the medium containing impurities. - excellent dynamic performance based on high natural frequency can achieve high position ring gain of main valve core, ensuring excellent static and dynamic response of main valve. - improve dynamic response - small pilot oil flow can also drive the main valve core to move rapidly - fail safe type a two position four-way solenoid valve is used to control the pilot flow short circuit, which can make the valve core in the limited safety position
